Question

I want to hide my mouse cursor after an idle time and it will be showed up when I move the mouse. I tried to use a timer but it didn’t work well. Can anybody help me? Please!

Here is a contrived example of how to do it. You probably had some missing logic that was overriding the cursor’s visibility:

public partial class Form1 : Form {     public TimeSpan TimeoutToHide { get; private set; }     public DateTime LastMouseMove { get; private set; }     public bool IsHidden { get; private set; }      public Form1()     {         InitializeComponent();         TimeoutToHide = TimeSpan.FromSeconds(5);         this.MouseMove += new MouseEventHandler(Form1_MouseMove);     }      void Form1_MouseMove(object sender, MouseEventArgs e)     {         LastMouseMove = DateTime.Now;          if (IsHidden)          {              Cursor.Show();              IsHidden = false;          }     }      private void timer1_Tick(object sender, EventArgs e)     {         TimeSpan elaped = DateTime.Now - LastMouseMove;         if (elaped >= TimeoutToHide && !IsHidden)         {             Cursor.Hide();             IsHidden = true;         }     } }
